Research Overview
Tesa is a synthetic analog of growth hormone-releasing hormone (GHRH) that binds to GHRH receptors on anterior pituitary somatotroph cells to stimulate growth hormone synthesis and secretion. Its structure includes the full 44-amino acid GHRH sequence with a trans-3-hexenoic acid modification at the N-terminus, which enhances enzymatic stability and extends its functional half-life relative to endogenous GHRH.
Researchers study Tesa to investigate the GHRH-GH-IGF-1 axis, a central endocrine signaling cascade that regulates somatic growth, metabolic homeostasis, and body composition. In the developer's non-clinical work the N-terminal modification slowed degradation of the peptide in rat, dog and human plasma in vitro, and daily injections raised plasma GH and IGF-1 in pigs, rats and dogs (Ferdinandi et al., Basic Clin Pharmacol Toxicol 2007); the peptide is used in pituitary function studies, receptor desensitization experiments, and GH pulse kinetics research.
Structurally, Tesa sits between the two other GHRH analogs on this site: Serma is the unmodified GHRH(1-29) fragment, CJC (No Dac) is a substituted GHRH(1-29) analog, and Tesa is the full 44-residue sequence with an N-terminal modification. No head-to-head half-life comparison of the three is cited here. Studies against CJC (No Dac) examine the effects of duration of action on GH pulsatility, while comparisons with Ipamorlin characterize GHRH versus ghrelin receptor pathways.
Laboratory applications include pituitary cell stimulation assays, GH secretion profiling, adipose tissue metabolism studies, and growth hormone axis research. Tesa is studied alongside its clinical research literature for understanding GHRH receptor pharmacology in research applications.

Frequently Asked Questions
- What is Tesa?
- Tesa is a synthetic analog of growth hormone-releasing hormone (GHRH). It consists of 44 amino acids and is used in research studying growth hormone secretion and related metabolic processes.
- How is Tesa different from Serma?
- While both are GHRH analogs, Tesa has a trans-3-hexenoic acid modification that may affect its stability and activity profile. Researchers often compare both compounds in their studies.
- Where can this research compound be purchased?
- This compound is available at PeptidesATX (peptidesatx.com), a U.S.-based research peptide supplier in Austin, Texas. All orders include a Certificate of Analysis, same-day shipping Monday through Thursday, and free shipping on orders over $200.
- Do you provide a Certificate of Analysis (COA)?
- Yes. Every lot listed on this site has a Certificate of Analysis from an independent laboratory (Horizon Analytical). The certificate reports the compound’s identity and purity by UPLC/MS (specification >98%; every lot currently listed measured at or above 99.05%), the measured quantity against the labeled amount, and appearance. Most lots also have a separate endotoxin report. The certificates do not include heavy-metal, sterility, residual-solvent or microbial testing, so they are not evidence that a lot is free of every possible contaminant. Every certificate can be viewed on the COA page before purchasing.
- How should I store this peptide?
- Store lyophilized (powder) vials at −20°C or colder, dry and protected from light. This is general laboratory practice for lyophilized peptides; it is not based on a product-specific stability study. Once reconstituted, keep the solution refrigerated at 2–8°C, protected from light, and use it promptly — solutions are less stable than the powder, and how long one remains usable depends on the peptide, the diluent and handling. Avoid repeated freeze–thaw cycles.
- How long does this peptide last after reconstitution?
- We have not performed product-specific stability studies, so no fixed shelf life is claimed for a reconstituted solution. Keep it refrigerated at 2–8°C, protected from light, avoid freeze–thaw cycles, and use it promptly; discard any solution that turns cloudy or shows particles. Bacteriostatic water contains 0.9% benzyl alcohol as an antimicrobial preservative for multi-draw vials; the preservative does not slow chemical degradation of the peptide itself.
- What is your shipping policy?
- Standard same-day shipping is $7.99 on all orders placed before 4 PM CT, Monday through Thursday. Orders of $200 or more ship free. All orders ship from Austin, TX with tracking provided. We ship to all 50 US states.
